Fracture Functions in Different Kinematic Regions and Their Factorizations
X. P. Chai, K. B. Chen, J. P. Ma +1
Fracture functions are parton distributions of an initial hadron in the presence of an almost collinear particle observed in the final state. They are important ingredients in QCD…
A Note on Pretzelosity TMD Parton Distribution
X. P. Chai, K. B. Chen, J. P. Ma
We show that the transverse-momentum-dependent parton distribution, called as Pretzelosity function, is zero at any order in perturbation theory of QCD for a single massless quark…
A Note on the -Factorization for Exclusive Processes
F. Feng, J. P. Ma, Q. Wang
We show in detail that the -factorization for exclusive processes is gauge-dependent and inconsistent.
Soft-Gluon-Pole Contribution in Single Transverse-Spin Asymmetries of Drell-Yan Processes
J. P. Ma, H. Z. Sang
We use multi-parton states to examine the leading order collinear factorization of single transverse-spin asymmetries in Drell-Yan processes. Twist-3 operators are involved in the…
Scattering at NLO Order in An Effective Theory
G. Y. Chen, J. P. Ma
We have proposed to use an effective theory to describe interactions of an -system. The effective theory can be constructed in analogy to the existing effective theory for…
